Dirty Rider

First off, great mod. Boggles the mind how a more robust mechanic like this is not\has not been implemented, so thank you. Now to the meat of the post. I've been playing this mod single player now and a buddy decided we should put in on the dedicated server, after looking of this thread it appeared to work, as long as both, the server and client had matching mod. Well he put the files in the proper folders (as far as we can tell) and nothing seams to happen. Some insight on what we could be missing would be great.
